Abstract Aim Invasive alien species (IAS) are recognized as major drivers of biodiversity loss, but few causal relationships between IAS and declines have been documented. In this study, we compare the distribution (Belgium Britain) abundance (Belgium, Britain Switzerland) formerly common widespread native ladybirds before after arrival Harmonia axyridis , a globally rapidly expanding IAS. Location Europe Methods We used generalized linear mixed‐effects models (GLMMs) to assess trends eight...
Inferences about introduction histories of invasive species remain challenging because the stochastic demographic processes involved. Approximate Bayesian computation (ABC) can help to overcome these problems, but such method requires a prior understanding population structure over study area, necessitating use alternative methods and an intense sampling design. In this study, we made inferences worldwide invasion history ladybird Harmonia axyridis by various genetics statistical methods,...
The Iranian species of the tribe Hyperaspidini Mulsant, 1846 (Coleoptera: Coccinellidae) are reviewed. current list includes 12 species, all placed in a single genus Hyperaspis Chevrolat, 1836. Hyperapsis asiatica Lewis, 1896 and H. pumila 1850 excluded from Coccinellidae. Diagnoses given. Images adult beetles diagnostic characters male genitalia distributed Iran shown. A key to identification is presented. Distribution records provided for each along with information on host plants prey...
Cold tolerance is a key determinant of poleward colonization in insects. However, the physiological basis underlying interspecific differences cold not fully understood. Here, we analyzed and metabolomic profiles warm- cold-acclimated phenotypes 43 Drosophila species representing latitudinal gradient from tropics to boreal zone. We found strong positive correlation between climatic variables associated with habitat seasonality temperature. Including effects acclimation, most have similar...
Abstract. In this study, the impact of acclimation (1 month at 15 °C vs. breeding 30 °C) and fluctuating thermal regimes (daily transfers from low temperatures to various higher for 2 h) on cold tolerance tropical beetle, Alphitobius diaperinus Panzer (Coleoptera: Tenebrionidae) was examined. Acclimation increased significantly duration survival ( Lt 50 ) a constant 5 (7.7 ± 0.3 days 9.7 0.5 days). Survival acclimated nonacclimated beetles slightly alternating °C/10 or °C/15 °C. When daily...
The tribe Coccinellini is a group of relatively large ladybird beetles that exhibits remarkable morphological and biological diversity. Many species are aphidophagous, feeding as larvae adults on aphids, but some also feed other hemipterous insects (i.e., heteropterans, psyllids, whiteflies), beetle moth larvae, pollen, fungal spores, even plant tissue. Several control agents or widespread invasive (e.g., Harmonia axyridis (Pallas)). Despite the ecological importance this tribe, little known...
Abstract The harlequin ladybird, Harmonia axyridis (Pallas, 1773), is native to Asia but has been introduced many countries, both intentionally and unintentionally. In the Middle East region, H. was so far only known from Iran Turkey. This study reports for first time a country with hot desert climate, Saudi Arabia. single specimen that found most likely result of unintentional release. Successful spreading in Arabia will be limited because high temperatures during summer scarcity prey...
The ambient temperature experienced during development is a crucial factor affecting survival and adult phenotype in ectotherms. Moreover, the exact response of individuals to different regimes frequently sex-specific. This sex-specific can result varying levels sexual dimorphism according conditions. majority studies have investigated effects on reared under constant regime throughout their whole preimaginal development, whereas information stage-dependent variation scarce. Here we...
The harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae) has rapidly spread in several continents over the past 30 years and is considered an invasive alien species. success of H. as invader often attributed to weak control by natural enemies. In this paper, we provide overview current knowledge on predators parasitoids axyridis. common feature that they directly kill exploited organisms. Currently available data show axyridis, displaying a variety chemical, mechanical,...
Most ladybirds (Coleoptera: Coccinellidae) possess chemical protection against predators and signal its presence by less or more conspicuous coloration, which can be considered as a warning. dotted pattern, althougn the number, shape, size of spots, well their colour, varies considerably. Almost all have characteristic general appearance (body shape). We these traits to used in ladybird recognition avian predators. In present study, we compared reactions (Parus major) caught wild, four...
We surveyed ladybirds (Coleoptera: Coccinellidae) in 10 stands of Scots pine (Pinus sylvestris), all monoculture 5-100 years old, western Slovakia, Central Europe, over two successive periods, October 2013 -March 2014 and 2015.The winter each period was exceptionally mild.Ladybirds were collected from the lower branches trees using beating trays present 61% 1040 samples (one sample containing 20 branches, 1 m long each).In total 3965 individuals species recorded.Non-conifer dwelling...
Some species of ladybird beetles (Coleoptera: Coccinellidae) mate both before and after overwintering. The purpose the pre-diapause mating was studied in alien invasive Harmonia axyridis (Pallas 1773). Our study demonstrates persistence high fecundity (daily oviposition rate 21 eggs per fertilized female during first month reproduction) fertility (85 % hatching) females H. long storage (up to eight months) at low temperature (6 °C). were not mated activation spring had rely on sperm supply...
Understanding the factors restricting distribution of some insect species to high altitudes is hindered by poor knowledge temporal changes in their cold hardiness during overwintering.We studied overwintering larvae fi ve Erebia butterfl ies (Lepidoptera: Nymphalidae: Satyrinae) differing altitudinal distribution: lowland E. medusa
Abstract Evolution of mimicry rings is reconstructed for the New World species cotton-stainer bugs (Dysdercus, Hemiptera: Pyrrhocoridae). Using a cladistic analysis 43 (including D. silaceus Doesburg, 1968 stat. nov. and modestus nov.), evolution colour patterns biogeographical history clade are hypothesized. Three probable obtained from analysis, together with data about their possible model–mimic or comimic–comimic structures: (a) ‘Yellow’ in north-western South America Andes (several...
